Primary Outcome Measures
NameTimeMethod
Main Objective: To determine the effects of sequential treatment between radium-223 and docetaxel on the percentage of symptomatic bone-only CRPC patients experiencing improvement or worsening in health-related quality of life (HRQoL).;Secondary Objective: To compare survival in patients treated with sequential therapy between radium-223 and docetaxel and to identify predictive factors of Radium-223 for clinical outcome in this patient population.;Primary end point(s): QoL clinical benefit;Timepoint(s) of evaluation of this end point: 36 months
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): 1) Progression-free survival (PFS)<br>2) Total progression-free survival (TPFS)<br>3) Overall survival (OS)<br>4) Safety <br>5) Identification of markers predictive to clinical outcome ;Timepoint(s) of evaluation of this end point: 1) 36 months<br>2) 36 months<br>3) 36 months<br>4) 36 months<br>5) 36 months
